Yes, the cell membrane is an organelle. It counts as an organelle as it has very specific functions in the cell, such as filtering what comes in and out of the cell.
protein is used for synthesis of many cell organelli and cell wall
single cell organism are microbes generally like bacteria which is a prokaryotic i.e. it did not have all the cellular organelli and the other example of single cells microbes is fungi which is an eukaryotic cell and have all the eukaryotic cellular organelli in themthere are another examples of single cell organims like protozoans and some algae which have eukaryotic cells
Cell membrane
A cell membrane is also known as a plasma membrane or cytoplasmic membrane. The cell membrane separates the interior of a cell from its outside environment. The main function of a cell membrane is to protect the cell from its surroundings.
the cell membrane is as flexible barrier outside of the cell.

The outer boundary of a general animal cell is the cell membrane.
There are multiple membranes in a cell. Two of them are the cell membrane and the nucleur membrane.
